title = "Field-orientation dependence of the specific heat of PrOs4 Sb12",
abstract = "The superconducting (SC) gap of the Pr-based skutterudite PrOs4 Sb12 has been investigated by means of field-angle-dependent specific heat C ( H, φ{symbol} ) experiments. At fixed temperatures, H was varied and rotated in the basal planes. A 4-fold oscillation of C ( H, φ{symbol} ) is observed in the entire H-T SC phase diagram. The minima are located along the [ 1 0 0 ] directions suggesting the excistence of gap nodes or minima along these directions. The oscillation amplitude | A | becomes maximum at H / Hc 2 ≈ 0.3. Below, | A | → 0. The temperature variation of | A | follows a quadratic dependence.",
